This International Standard defines the design, safety and operation characteristics of gaseous hydrogen land
vehicle (GHLV) refuelling connectors. GHLV refuelling connectors consist of the following components, as
applicable.
- Receptacle and protective cap (mounted on vehicle).
- Nozzle.
This International Standard applies to refuelling connectors which have working pressures of 11 MPa, 25 MPa
and 35 MPa and 70 MPa, hereinafter referred to in this International Standard as the following:
- H11 – 11 MPa at 15 ºC
- H25 – 25 MPa at 15 ºC
- H35 – 35 MPa at 15 ºC
- H35HF – 35MPa at 15 ºC (high flow for commercial vehicle applications)
- H70 – 70 MPa at 15 ºC
Nozzles and receptacles that meet the requirements of this International Standard will allow GHLVs to be
fuelled by dispenser stations with nominal working pressures equal to or lower than the vehicle fuel system
working pressure.
This International Standard is intended to be used for certification purposes.
